647860 ÷ 55 
The aim is to understand the frequency of 55 in 647860.

Advancing to step 1:
When dividing 6 by 55, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 55

Step 2:
64 divided by 55 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 55 from 64 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 55

Moving on to step 3:
55 can be fit into 97 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 55 from 97 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 55

Let's proceed to step 4:
428 divided by 55 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtract 385 from 428 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 55

Let's proceed to step 5:
When dividing 436 by 55, we get 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 1177.0
Deduct 385 from 436 and we're left with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 55

Going ahead to step 6:
If we divide 510 by 55, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 11779.0
Subtracting 495 from 510 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
150 divided by 55 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 11779.2
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 55 fits into 400 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 11779.27
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 11779.272
Deduct 110 from 150 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 55 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 11779.2727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
The number 55 fits into 150 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 11779.27272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 11779.272727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
When dividing 150 by 55, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 11779.2727272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
55 goes into 400 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 11779.27272727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 11779.27272727 with a remaining 1.5e-08.
